Batcave

The idea of a secondary Batcave in Arkham Asylum first appeared during the No Man's Land saga.

Batman: The Animated Series

Batman, Joker and Harley Quinn are voiced by Kevin Conroy, Mark Hamill and Arline Sorkin respectively, who reprise their roles from the critically acclaimed Batman: The Animated Series.

The story is written by Paul Dini who, as well as having contributed to the comics, was a writer on the series.

If Batman is killed by Bane, one of the death cut scenes shows Bane breaking his back. He also taunts Batman during battle, yelling "I will break you" and making a kneeing motion. This is a reference to the Knightfall storyline, where Bane actually broke Batman's spine.

References to Arkham Asylum: A Serious House on Serious Earth

The game references Grant Morrison's Arkham Asylum: A Serious House on Serious Earth several times:

Amadeus Arkham, the asylum's founder, is mentioned and has a bio.

The insect motif that appears on the "Spirit of Arkham" artifacts is inspired by the book.

In the garden, there is the statue of Saint Michell (an angel with a spear).

There is also a reference to the gory demise of Amadeus' wife and child.

And finally, the basic premise of the book is the same (the Joker takes over Arkham and its inmates, including several Bat-villains, run amok).
